Fix inventory for test_dir_inventory

It came up that fixing this unit test may relate to another ticket that is open. This work allows us to uncomment this unit test by fixing how we pars variables allowing a quoted variable to contain a '#'.

Work also went into cleaning up some of the test data to clarify what was working.

Lastly work went into cleaning up formatting so that the code is easily read.
Add credential parameters to the GCE modules.

In order to simplify the workflow with the GCE modules, it's now
possible to add the parameters and project name as arguments to the
various GCE modules.

The inventory plugin also returns the IP of the host in
`ansible_ssh_host` so that you don't have to specify IPs into the
inventory file.

Some update to the documentation are also added.

Closes #5583.
